Lumicar Care is a car wash on Avonhead Road in Christchurch's Avonhead, holding a perfect 5.0 rating on Google.
The difference between a wash that protects your paint and one that slowly marks it comes down to technique. A careful operator pre-rinses thoroughly so grit isn't dragged across the panels, works with clean mitts rather than a tired sponge, and finishes with a proper hand-dry to keep water spots away. Those faint swirl marks you notice in sunlight on older cars usually come from shortcuts at the wash rather than from the road. With Canterbury's nor'wester settling fine dust on everything within a day, regular gentle washes beat the occasional deep clean for keeping paintwork in good nick.
